ULTRASONIC THICKNESS GAUGING

One day (8 hours)

TRAINING OBJECTIVES: This one day course is intended to provide the basic theory of ultrasonic technology to a degree that the participants will have an understanding of ultrasonic thickness gauging. Participants in this hands-on workshop will be able to better understand the pitfalls of ultrasonic thickness gauging with respect to material velocities, surface roughness and geometrical configurations.
